The International Maize and Wheat Improvement Center (CIMMYT) is offering a new set of elite, improved maize hybrids to partners for commercialization in the tropical lowlands of Latin America and similar agro-ecological zones. National agricultural research systems (NARS) and seed companies are invited to apply for licenses to commercialize these new hybrids, in order to bring the benefits of the improved seed to farming communities. In some countries, depending on the applicable regulatory framework for commercial maize seed, successful applicants may first need to sponsor the products through the national registration / release process prior to commercialization.
The deadline to submit applications to be considered during the first round of allocations is September17, 2021. Applications received after that deadline will be considered during the following round of product allocations.
Information about the newly available CIMMYT maize hybrids from the Latin America breeding program, application instructions and other relevant material is available in the CIMMYT Maize Product Catalog and in the links provided below.
Applications must be accompanied by a proposed commercialization plan for each product being requested. Applications may be submitted online via the CIMMYT Maize Licensing Portal in English or Spanish.
Alternatively, applications may be submitted via email to GMP-CIMMYT@cgiar.org using the PDF forms available for download at the links below. Each applicant will need to complete one copy of Form A for their organization, then for each hybrid being requested a separate copy of Form B. (Please be sure to use these current versions of the application forms.)

The COVID-19 pandemic has exposed vast inequalities when it comes to food security. But there is an even larger and more concerning crisis waiting for us: global food shortages caused by climate change.
Nobody knows when or how hard it will hit, but we inch closer each year with new temperature records, the spread of pests, and emerging crop diseases. We are already seeing the beginning of this future crisis. Climate-induced food price hikes have caused political turmoil in the Middle East, while climate-related disasters have been linked with mass human migration in South Asia.
Every seed company and crop research center worldwide is preoccupied with the race to breed hardier crops to keep pace with the demands of a growing population as circumstances become increasingly challenging. But the truth is, this is a relay race, and yet the crop research field is running 100-meter sprints in different places at different times.
For every scientific advance, other areas of crop research go under-resourced and are technology poor, with asymmetries in research investment creating islands of knowledge that are disparate and disconnected. Â These research asymmetries hold back crop improvement as a whole, contributing to climate-induced crop failure and the political turmoil that ensues when staple foods become scarce.
While it is common for academic crop scientists to share ideas and collaborate with industry, it is far less typical for major seed companies to cooperate with each other.
If the public and private sectors are to have any chance of outrunning climate change, industry must shift toward investing in mutually beneficial research and development to pool resources and build on every gain, in the interests of the whole.
In an unprecedented first step that reveals just how much pressure the sector feels about the daunting task ahead, some of the crop industryâs main players and competitors â including Syngenta, BASF, Corteva and KWS â recently shared their insights into the gaps in existing crop science.
The shortcomings identified that hold back the crop industry from addressing the looming food crisis have three features in common. They are all under-represented in scientific literature, are likely to boost productivity across a wide range of crops and environments, and crucially, the research is fundamental enough to be âpre-competitive,â or valuable without jeopardizing individual business outcomes.
For example, although scientists have made progress towards improving the potential of crucial processes in crop development, like photosynthesis, other gaps in knowledge must be filled to ensure that this translates into improved yield, especially under unstable environments.
Such research is critical to ensuring reliable harvests across a range of crops, and can be conducted without infringing the intellectual property or proprietary technology of any single company.
However, accessing research funding can be surprisingly difficult. Public research budgets are shrinking, their funds are at risk of being re-appropriated, and collaboration is not the industry standard.
New funding models, such as public-private partnerships, can collectively address knowledge gaps to avoid potential catastrophes for society at large.
This approach has already proven fruitful. The public-private consortium âCrops of the Future Collaborativeâ brings competitors together to jointly fund research into the characteristics crops need to adapt to a changing future.
Industry matched the Collaborativeâs initial $10 million investment by the Foundation for Food & Agriculture Research to work on corn that survives in drought conditions and leafy greens that are resistant to pests.
Conducting this research jointly drastically improves crop efficiency and the technological toolbox available to breeders and other crop scientists, passing the baton in the race towards a food secure future.
Increasing the global food supply through research and development is the most achievable and sure approach to avoid a global food crisis, and comes with historically high returns on investment. Furthermore, scientists can tap into a global infrastructure of researchers across public and private sectors, international organizations, and the millions of farmers worldwide who have willingly collaborated over the last half century to provide enough food for all.
Failure to collaborate will ultimately result in unsustainable food systems, which not only renders seed companies obsolete but threatens a prerequisite of civilization: food security.
The private sector has the knowledge and resources to redefine the race. Rather than competing against one another, the crop industry must join forces to compete instead with climate change. And it is a contest we can only win if all players work together.

Artificial Intelligence (AI) and Machine Learning (ML) are increasingly being applied across a diverse range of disciplines. Many aspects of our lives and work are now benefiting from these technologies. Disease recognition, for both human and plant health, is no exception. Ever more powerful AI/ML techniques are now opening up exciting opportunities to improve surveillance, monitoring and early warning for disease threats.
âThe value of tools like PlantVillage Nuru is that we can greatly increase the coverage and speed of surveillance,â says CIMMYT scientist and disease surveillance expert Dave Hodson. âTrained pathologists can only visit a limited number of fields at fixed times in the season. With tools like Nuru, extension agents and farmers can all contribute to field surveys. This can result in much faster detection of disease outbreaks, better early warning and improved chances of controlâ.
New advances in AI/ML technology are now promising even greater improvements in these already powerful tools. CIMMYT scientists have had a long-standing partnership with the PlantVillage group, working to try and develop improved diagnostics for important wheat diseases such as rusts and blast. Considerable progress in developing automated diagnostics for wheat diseases has already been made, but the introduction of advanced image segmentation and tiling techniques promises to be a major leap forward.
âAdvances in computer science are constantly happening and this can benefit the mission of CGIAR and PlantVillage,â explains David Hughes, Dorothy Foehr Huck and J. Lloyd Huck Chair in Global Food Security at Penn State and founder of PlantVillage.
âImage segmentation and tiling techniques are a great example. They used to require intensive computing requirements. Now due to advances in computer science these powerful techniques are becoming more accessible and can be applied to plant disease problems like wheat rusts.â
By using these image segmentation and tiling techniques the developers at PlantVillage are now seeing a major improvement in the ability to automatically and accurately detect wheat rusts from in situ photos. âWe could not identify rusts with the older approaches but this segmentation and tiling tool is a game changer. The computer goes pixel by pixel across the images which is well suited to diseases like rusts that can be spread across the leaf or stem of the plant. The computer now has a much more powerful search algorithm.â
The team led by Pete McCloskey, lead A.I. engineer at Plant Village, actually used a multi-step process. First they removed the background to help the machine focus in on the leaf. They then digitally chopped the leaf into segments giving the AI a further helping hand so it can focus in and find the rust. Then the whole leaf is stitched together and the rust is highlighted to help humans working in the PlantVillage cloud system.
Fig: Examples of manual, hand labelled images (top rows) compared to AI generated images using segmentation and tiling (bottom rows) for stem rust (upper image panel) and stripe rust (lower image panel).
This exciting new development in rapid, accurate field detection of wheat rusts now needs validation and improvement. As with all AI/ML applications, numbers of images included in the models really improve the quality of the final predictions. âThe success of any machine learning model is rooted in the quality and quantity of the data it is trained on,â notes McCloskey. âTherefore, it is critical to source vast and diverse amounts of high-quality images from around the world in order to develop a global wheat rust recognition system.” In this aspect we hope that the CIMMYT global wheat community can help drive the development of these exciting new tools forward.
CIMMYT and PlantVillage are hoping to expand the current wheat rust image dataset and as a result produce an even more valuable, public good, disease detection tool. Given the extensive field work undertaken in wheat fields around the world by CIMMYT staff and partners, we hope that you can help us. Any photos of wheat rusts (stem, stripe and leaf rust) in the field would be valuable.
We would like to have images with one infected leaf or stem per image, it should be vertical in the image so you can see the whole leaf or stem segment. The leaf or stem needs to be in focus and should be roughly centered in the image. It helps to hold the tip of the leaf away from the stem, so it is outstretched and flat. Ideally for training data, the leaf should have only one type of rust and no other disease symptoms. It is okay to have other leaves/stems/soil/sky in the background. It is also okay to have hands and other body parts in the image.
Below are some example images. Any images can be uploaded here.

As the world turns its attention to the policy-shaping discussions during this weekâs Pre-Summit of the UN Food System Summit, the need for science and innovation to advance the transformation of food, land and water systems is clear.
The International Maize and Wheat Improvement Center (CIMMYT), with its 50-year track record of impact, success and high return on investment, is essential to these efforts.
Our new institutional brochure, Maize and wheat science to sustainably feed the world, links CIMMYTâs mission, vision and excellence in science to the urgent needs of a world where an estimated tenth of the global population â up to 811 million people â are undernourished.
CIMMYT is also a crucial wellspring of response capacity to CGIAR â the largest global, publicly funded research organization scaling solutions for food, land and water system challenges.
Maize and wheat science to sustainably feed the world explains why we do what we do in light of these challenges.
CIMMYT leads maize and wheat research for food systems that deliver affordable, sufficient, and healthy diets produced within planetary boundaries.
Our research is focused on smallholder farmers in low- and middle-income countries and on improving the livelihoods of people who live on less than $2 a day.
CIMMYT science reaches them through innovation hubs, appropriate technologies, sustainable sourcing, and helps to address their needs and challenges through public policy guidance.
Applying high-quality science and strong partnerships, CIMMYT works for a world with healthier and more prosperous people, free from global food crises and with more resilient agri-food systems.
Back-to-back droughts followed by plagues of locusts have pushed over a million people in southern Madagascar to the brink of starvation in recent months. In the worst famine in half a century, villagers have sold their possessions and are eating the locusts, raw cactus fruits, and wild leaves to survive.
Instead of bringing relief, this yearâs rains were accompanied by warm temperatures that created the ideal conditions for infestations of fall armyworm, which destroys mainly maize, one of the main food crops of sub-Saharan Africa.
Drought and famine are not strangers to southern Madagascar, and other areas of eastern Africa, but climate change bringing warmer temperatures is believed to be exacerbating this latest tragedy, according to The Deep South, a new report by the World Bank.
Up to 40% of global food output is lost each year through pests and diseases, according to FAO estimates, while up to 811 million people suffer from hunger. Climate change is one of several factors driving this threat, while trade and travel transport plant pests and pathogens around the world, and environmental degradation facilitates their establishment.
Crop pests and pathogens have threatened food supplies since agriculture began. The Irish potato famine of the late 1840s, caused by late blight disease, killed about one million people. The ancient Greeks and Romans were well familiar with wheat stem rust, which continues to destroy harvests in developing countries.
But recent research on the impact of temperature increases in the tropics caused by climate change has documented an expansion of some crop pests and diseases into more northern and southern latitudes at an average of about 2.7 km a year.
Prevention is critical to confronting such threats, as brutally demonstrated by the impact of the COVID-19 pandemic on humankind. It is far more cost-effective to protect plants from pests and diseases rather than tackling full-blown emergencies.
One way to protect food production is with pest- and disease-resistant crop varieties, meaning that the conservation, sharing, and use of crop biodiversity to breed resistant varieties is a key component of the global battle for food security.
CGIAR manages a network of publicly-held gene banks around the world that safeguard and share crop biodiversity and facilitate its use in breeding more resistant, climate-resilient and productive varieties. It is essential that this exchange doesnât exacerbate the problem, so CGIAR works with international and national plant health authorities to ensure that material distributed is free of pests and pathogens, following the highest standards and protocols for sharing plant germplasm. The distribution and use of that germplasm for crop improvement is essential for cutting the estimated 540 billion US dollars of losses due to plant diseases annually.
Understanding the relationship between climate change and plant health is key to conserving biodiversity and boosting food production today and for future generations. Human-driven climate change is the challenge of our time. It poses grave threats to agriculture and is already affecting the food security and incomes of small-scale farming households across the developing world.
We need to improve the tools and innovations available to farmers. Rice production is both a driver and victim of climate change. Extreme weather events menace the livelihoods of 144 million smallholder rice farmers. Yet traditional cultivation methods such as flooded paddies contribute approximately 10% of global man-made methane, a potent greenhouse gas. By leveraging rice genetic diversity and improving cultivation techniques we can reduce greenhouse gas emissions, enhance efficiency, and help farmers adapt to future climates.

We also need to be cognizant that gender relationships matter in crop management. A lack of gender perspectives has hindered wider adoption of resistant varieties and practices such as integrated pest management. Collaboration between social and crop scientists to co-design inclusive innovations is essential.
Men and women often value different aspects of crops and technologies. Men may value high yielding disease-resistant varieties, whereas women prioritize traits related to food security, such as early maturity. Incorporating womenâs preferences into a new variety is a question of gender equity and economic necessity. Women produce a significant proportion of the food grown globally. If they had the same access to productive resources as men, such as improved varieties, women could increase yields by 20-30%, which would generate up to a 4% increase in the total agricultural output of developing countries.
Practices to grow healthy crops also need to include environmental considerations. What is known as a One Health Approach starts from the recognition that life is not segmented. All is connected. Rooted in concerns over threats of zoonotic diseases spreading from animals, especially livestock, to humans, the concept has been broadened to encompass agriculture and the environment.
This ecosystem approach combines different strategies and practices, such as minimizing pesticide use. This helps protect pollinators, animals that eat crop pests, and other beneficial organisms.
The challenge is to produce enough food to feed a growing population without increasing agricultureâs negative impacts on the environment, particularly through greenhouse gas emissions and unsustainable farming practices that degrade vital soil and water resources, and threaten biodiversity.
Behavioral and policy change on the part of farmers, consumers, and governments will be just as important as technological innovation to achieve this.
The goal of zero hunger is unattainable without the vibrancy of healthy plants, the source of the food we eat and the air we breathe. The quest for a food secure future, enshrined in the UN Sustainable Development Goals, requires us to combine research and development with local and international cooperation so that efforts led by CGIAR to protect plant health, and increase agricultureâs benefits, reach the communities most in need.

In 2020, faced with the extraordinary challenges posed by the COVID-19 pandemic, MAIZE continued its mission to strengthen maize-based agri-food systems while improving the food security and livelihoods of the most vulnerable, especially resource-constrained smallholder farmers and their families.
MAIZE and its partners made great advances in the development of improved stress-tolerant maize varieties, the battle against fall armyworm (including the announcement of three first-generation fall armyworm-tolerant maize hybrids), testing and promoting of conservation agriculture and sustainable intensification, and in deepening our grasp of how to best empower women in the quest for gender equality and social inclusion in maize-based agri-food systems.
Led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Institute of Tropical Agriculture (IITA) as its main CGIAR Consortium partner, MAIZE focuses on increasing maize production for the 900 million poor consumers for whom maize is a staple food in Africa, South Asia and Latin America.
We are proud to present highlighted impacts from WHEATâs research in our 2020 Annual Report, showcasing the shared accomplishments through global partnerships for the eighth year of the program.
In 2020, the COVID-19 crisis devastated communities, economies, and livelihoods, especially of the worldâs most vulnerable populations. At the same time, climate change continued to threaten wheat systems around the world. Under unprecedented challenges, WHEAT scientists and partners responded swiftly, generating new research evidence, forming new partnerships, and improving access to conservation agriculture and farm mechanization technologies.
This web-based report focuses on some of the major impacts the program has had on sustainable intensification, gender and social inclusion, and technological innovations for more productive wheat-based farming. Although they are reported for 2020, these impacts reflect years of dedicated science and strong collaborative relationships with partners.
We are deeply grateful for our partners in the science, research, policymaking, and funding communities who have allowed us to continue our work in the face of urgent and powerful challenges. We hope you enjoy this yearâs Annual Report as we look back upon our outcomes and achievements in 2020 and set our targets for the future.
Today the Board of Trustees of the International Maize and Wheat Improvement Center (CIMMYT) announced leadership changes.
The Board approved the appointment of Martin Kropff, current Director General of CIMMYT, as Global Director of Resilient Agrifood Systems of CGIAR. He will play a critical role in enabling an effective transition to the new structure of CGIAR and implementing the CGIAR 2030 Research and Innovation Strategy. In this role, Kropff will be hosted by the CGIAR System Management Organization and will be based in Montpellier, France.
âWe congratulate Dr. Kropff on his new position. We are convinced that he will bring to CGIAR the same excellence in science, innovation and effective management that he brought to CIMMYT,â said Board of Trustees Outgoing Chair Nicole Birrell, who completes her term in October this year.
âThrough my tenure as CIMMYT Director General, we built a strong and committed team. I am sure that â with the support of the Management Committee, the Executive Committee, the Board, and the three CGIAR Science Group directors â the work of CIMMYT will find a good place in CGIAR,â said Martin Kropff.
New Director General ad interim
Effective July 1, 2021, in accordance with CIMMYTâs Constitution, the Board of Trustees appointed Bram Govaerts as CIMMYTâs Director General ad interim.
Govaerts has been part of the CIMMYT family since 2007. He is Chief Operating Officer and Deputy Director General for Research (Sustainable Production Systems and Integrated Programs) ad interim. He is also the director of CIMMYTâs Integrated Development Program.
Govaerts is renowned for pioneering, implementing and inspiring transformational changes for farmers and consumers in meeting sustainable development challenges. He brings together multi-disciplinary science and development teams to integrate sustainable, multi-stakeholder and sector strategies that generate innovation and change in agri-food systems.
âOn behalf of the full Board, we want to thank Dr. Govaerts for his leadership and willingness to ensure that the Center, our research and our operations continue to run smoothly to serve our mandate and mission, as well as the broader One CGIAR vision,â said Board of Trustees Incoming Chair Margaret Bath.
âThe world needs CIMMYT and our mission now more than ever, to respond to the challenges that are ahead. We are ready to take up this role, as CIMMYT has done ever since Norman Borlaug and his talented team started their work in the service of the poorest. Let us continue celebrating his legacy by generating further impact through our science,â Govaerts said.
The fall armyworm is an invasive pest that eats more than 80 different crops, but has a particular preference for maize.
It is native to the Americas. It was first reported in Africa in 2016, and quickly spread throughout the continent. It reached India in 2018. It has since been reported in many other countries across Asia and the Pacific, and it reached Australia in 2020.
Millions of families in these regions are highly dependent on maize for their income and their livelihoods. If the fall armyworm keeps spreading, it will have disastrous consequences for them.
Scientists at CIMMYT have been working hard to find solutions to help farmers fight fall armyworm. Researchers have developed manuals for farmers, with guidelines on how to manage this pest. They have also formed an international research consortium, where experts from diverse institutions are sharing knowledge and best practices. Consortium members share updates on progress in finding new ways to tackle this global challenge. Scientists are now working on developing new maize varieties that are resistant to fall armyworm.
The fall armyworm canât be eradicated â it is here to stay. CIMMYT and its partners worldwide will continue to work on this complex challenge, so millions of smallholder farmers can protect their crops and feed their families.
We began 2020 with grim news of the COVID-19 pandemic spreading from country to country, wreaking havoc on national economies, causing countless personal tragedies, and putting additional pressure on the livelihoods of the poor and hungry.
The global crisis exposed the enormous vulnerability of our food system.
If we have learned anything from the past year, it is that we need to urgently invest in science for renewed food systems that deliver affordable, sufficient, and healthy diets produced within planetary boundaries.
During this time, the dedication and resilience of the CIMMYT community allowed us to continue making important advances toward that vision.
We hope you enjoy reading our stories and will join us in actively working towards resilience, renewal and transition in our agri-food systems, to ensure that they are strong in the face of current and future crises.
At the 8th World Congress on Conservation Agriculture (8WCCA), Martin Kropff, Director General of CIMMYT, argued that “agriculture cannot take a toll on the environment”, praising conservation agriculture for its contribution to building resilience to drought.

The three rust diseases, yellow (stripe) rust, black (stem) rust, and brown (left) rust occur in most wheat production environments, causing substantial yield losses and under serious epidemics, can threaten the global wheat supply.
CIMMYT is one of the largest providers of elite germplasm to national partners in over 80 countries. CIMMYT nurseries, known for research in developing adaptive, high-yielding and high-quality germplasm, also carry resistance to several biotic and abiotic stresses, such as rust disease.
Through years of research and experience, CIMMYT has found that durable control of wheat rusts can be achieved by developing and deploying wheat varieties with complex adult-plant resistance (APR). A combination of both conventional and modern technologies in APR will enable breeders to address the problem of rusts and other diseases and continue progress in delivering higher genetic gains, a key goal of the Accelerating Genetic Gains in Maize and Wheat (AGG) project.
At the International Maize and Wheat Improvement Center (CIMMYT), staff are one of our most important assets. We anchor our commitment to diversity and inclusion through our vision, mission and organizational strategy. We interpret workplace diversity as understanding, accepting and valuing all aspects of oneâs identity, including gender.
Scientists such as Itria Ibba, head of the Wheat Chemistry and Quality Laboratory, Thokozile (Thoko) Ndhlela, maize line development breeder, and Huihui Li, quantitative geneticist, empower the rest of the maize and wheat research community to do more for those who need sustainable food systems the most.
It wasnât easy to find a convenient time for the four of us to have a conversation â me, because of COVID-19 travel restrictions, from the Netherlands, Itria in Mexico, Thoko in Zimbabwe and Huihui in China â but we managed. I enjoyed hearing about their work, what sparked â and continues to spark â their passion for maize and wheat research and had the chance to share some thoughts about where the CGIAR transition is taking us.
Martin Kropff, Itria Ibba, Thoko Ndhlela and Huihui Li share a discussion over Zoom. (Photo: CIMMYT)
Martin Kropff: Hello Itria, Huihui and Thoko, great to see you! Iâd love to hear more about what you do. Why do you think your work is important in this day and age?
Itria Ibba: Hello Martin! I lead the [CIMMYT] Wheat Chemistry and Quality Laboratory. I am very passionate about my work, which I believe is very important.
In the lab we work both on the improvement of wheat technological and nutritional quality. Both of these aspects are fundamental for the successful adoption of a wheat variety and, of course, to promote a healthy and nutritious diet. Development of nutritious varieties is especially important because â especially in developing countries â the basic diet doesnât provide all the micro and macronutrients necessary to live a healthy life. Since my focus is wheat, a staple crop that is mainly used for human consumption, I think the work that I am doing can actually have a direct and real impact on the lives of many people.
Kropff: It is important that you â on the quality side of the work â can give feedback to the breeders, and they listen to you. Is it happening?
Ibba: I believe that yes. Of course, quality cannot be the only target in the selection process where several other traits such as yield potential, disease resistance and tolerance to abiotic stresses have to be considered. However, especially for wheat, quality needs to be considered because it is strictly associated with the economic value of a specific variety and plays a fundamental role throughout the whole wheat value chain. The feedback we are giving is being taken positively. Of course, it could be âheardâ more.
Kropff: If I may ask, do you think youâre being treated as a scientist regardless of your gender? Or does it matter?
Ibba: Personally, I have always felt that I was respected, in my lab and in my team, especially at CIMMYT. At the beginning, I had some concerns because I am a bit young⊠Mainly because of that, yes, but not because I am a woman. I cannot say anything bad from that perspective.
Kropff: I think that young people must have the future in our organization. Sometimes when people get older â I try not to be like that, but I am also getting older â they think that they know everything and then you have to be very careful, because the innovations are mostly coming from young people. But young minds come up with new ideas. What about your work, Huihui? You are contributing in a completely different way than Itria and Thoko, and you are coming from a mathematical point of view. When I see you, I always think about math.
Li: Yes, due to my major, sometimes I feel like I am a stranger working in an agricultural research organization. Because I canât breed new varieties, for example. So, whatâs my position? I ask myself: how can I have a successful career in agriculture? But I think that in this new era, this new digital era, I can do more.
Kropff: Data, data, data!
Li: Yes! We can do smart agriculture based on big data. We can do a lot of things with prediction, so that breeders can save time and effort. Maybe we cannot breed the varieties directly or we cannot publish our new findings in high impact journals, but we can play an essential role for this work to be successful. I think thatâs my added value: to be useful to breeders.
Kropff: And you are! Thoko, what about you?
Ndhlela: Iâm a maize breeder. Iâm responsible for two product profiles in southern Africa and these are extra early, early and nutritious maize. I feel like my work is very important, given that I am focusing on developing and deploying nutritious and stress-tolerant maize varieties to people who rely on maize as a staple food crop. White maize is the one that is mainly consumed and yet it doesnât contain any of the micronutrients such as vitamin A, zinc, iron. We are working towards closing that gap where people have limited or no access to other foods that contain those micronutrients. If we provide them with maize that is nutritious, then we close that gap and addressing the issue of malnutrition. It is especially critical, for young children. According to UNICEF, 53% of the mortalities in children globally are due to micronutrient deficiencies. My work aims to address to a greater extent the problems that farmers face.

Kropff: Are you working on provitamin A maize?
Ndhlela: Yes!
Kropff: Itâs orange right? How are consumers adopting it? Does that require extra marketing activities?
Ndhlela: Yes, because in most countries where maize is a popular staple food, people use yellow maize mostly for livestock feeds. But when it comes to the main food, they mainly use white maize. So there has to be that extra effort. We have been working with HarvestPlus on that front, and so far in southern Africa weâve made good strides in terms of getting people to accept the maize.
Back in the day, when they were first introduced to the idea of eating yellow maize as main food, that maize came from food relief and not in a good state, so there was that negative attitude, which they remembered when we came in with vitamin A maize [which has a yellow color]. We told them, âThis is differentâ and the fact that we did demos, they grew the maize, they harvested and consumed it, led to their acceptance of it. Right now, we have so much demand for seed, especially across southern Africa. Seed companies that we work with say that the seed is sold out and people are still looking for it.
Kropff: Iâm very happy to hear this. We have to make sure that what we do is demand-driven, right? And on your role as a woman in research in Zimbabwe. Do you feel like you are taken seriously as a scientist?
Ndhlela: I really do, yes. I am really given space to be myself, to do my work and have that impact on the ground.
Ibba: Martin, I have a question regarding One CGIAR. Will there be any changes within CIMMYT regarding redistribution of research areas? Will some of the research areas change the research focus or implement new research groups and strategies?
Kropff: I could talk for five hours about this. CGIAR has big plans to change the structure, to change the initiatives, to change everything this year.
I believe that CIMMYT is strong, we have a lot of impact. The quality of our work is really high, and I want to make sure that CIMMYTâs work â your work â finds a solid landing in the new CGIAR.
Theyâre envisioning a restructuring in three large science groups. Several Directors General suggest that we shouldnât start breaking everything up but that we take whole programs as we have them now and bring them into the new science groups. Itâs complicated but everyone wants the CGIAR to be successful.
In terms of research, what we do as CIMMYT already provides solutions, for example, the Integrated Development Programs, such as CSISA, MasAgro, SIMLESA. This has now been taken over by the whole CGIAR. These are programs where you work with national systems and you look at what is important to them, and where innovation is needed. Not focusing on single solutions but integrated solutions from different disciplines. When the research needs come directly from the stakeholders, we become more demand-driven. And that makes life even more exciting.
I think that when we listen to our stakeholders, there will always be a maize and wheat component [in agricultural research]. When we interviewed them in 2020, they stated that things [that are on top of their wish list for agricultural research and development are] breeding, agronomy, big data, and wheat, maize and rice.
I always say: what we need is food systems that deliver affordable â you said it already, Thoko â sufficient and healthy diets produced within planetary boundaries. And for all those criteria, wheat and maize are key because they are efficient, they are produced very well, they provide a good basis of nutrition, and you can produce them within planetary boundaries.
But, back to you. Could you share a story or anecdote about a turning point or defining moment in your work?
Ibba: Personally, Iâve had different turning points that led me to this career but I believe that one of the most important moments for me was when I started my PhD in Crop Science at Washington State University. There for the first time in my scientific career I understood the importance of working together with breeders, molecular scientists, cereal chemists and even with food companies in order to deliver a successful product from farmers all the way to consumers. The research done there had a real impact that you could see and I loved it. Also for this reason, I am happy to now work at CIMMYT because this happens here, as well, but at a bigger scale. You can clearly see that the work and research you do are directly used and go into new wheat lines and new varieties which are grown by different farmers across the world. Itâs amazing. Thatâs what I think had a bigger impact for me.

Ndhlela: I think the biggest moment in my work was when I was first employed as a scientist at CIMMYT. I always looked at CIMMYT scientists as role models. I remember many times that CIMMYT jobs were being advertised for technicians, and people would say, âOh, this is yours now!â and I told them, âNo, no, no, I will only join CIMMYT as a scientist.â And I waited for that moment. And it came and was a turning point in my career and I really thought that now I can express myself, do my work without limitations. And to reach impact!
Another great moment in my work is when I hear that hundreds of farmers are growing and consuming the varieties that I am involved in developing and deploying. I really want to hear people talking of impact: how many tons of certified seed is being channeled from seed companies to the growers, and how many peoplesâ lives are we improving. I think that really defines my work. If the varieties donât get to the farmer, then it is just work going to waste.
Li: Sometimes I feel inferior because I canât breed a variety, or have big papers in agriculture-related journals, but one day I looked up my citation of my publications and I felt self-satisfied. I could feel my impact. Actually, several of my papers are highly cited; my total citation is more than 3,000 right now.
Kropff: Oh good!
Li: Yes! That means that my work has impact and many people are using the algorithm I developed to have even more impact. Papers that cite my work are published in Science and Nature, Nature Genetics, etc. I feel useful and like my work plays an essential role in research.
Kropff: Thatâs the thing: thereâs impact in science and impact in farmersâ fields and at CIMMYT it comes together. Colleagues at CIMMYT are taking your results and using them to make a difference through crop variety improvement and other things.
Ndhlela: How do you think that One CGIAR will help strengthen our research towards the Sustainable Development Goals across the geographies where we work?
Kropff: I have always promoted the idea of âOne CGIARâ. Even before joining CIMMYT. But it is complicated because weâre bringing 13 CGIAR Centers together. I saw it at Wageningen University: when you have one organization, you can be so much stronger and more visible, globally.
Because together we [One CGIAR] are the global international organization for agricultural research. We add something [to our global partners such as] the Food and Agriculture Organization of the UN (FAO) which works on agricultural policy, and IFAD that has international development programs and World Food Programme which delivers food â most of it staple crops â to those who need it the most. But supplying food is not a sustainable approach, we want to have sustainable food systems in those countries, so that people can produce their own food. Thatâs where research is necessary, and knowledge is necessary.
I am super proud that the wheat and maize and agronomy work we do is so well adopted. Farmers are adopting our varieties across the globe. These are new varieties Iâm talking about â this is key â which are on average 10 years old and they respond to current challenges happening on the ground. Regarding your work, Thoko, with maize, I just got data from Prasanna [CIMMYTâs Maize Program and CGIAR Research Program on Maize Leader, Prasanna Boddupalli] that farmers are growing drought-tolerant maize and other maize varieties from CIMMYT on 5 million hectares in eastern and southern Africa! All of this is because of a good seed systems approach with the private sector: small seed companies delivering our varieties scaling our great breeding work. Taking it to the farmers!
I think that the work that we do is super important to reach the Sustainable Development Goals. Number one ââ well, itâs number two, but for me it is the first ââ is ending hunger. Because when youâre hungry, you cannot think or live normally. Poverty is also an incredibly important challenge. But I would put hunger as number one. I donât think any of us here have had real hunger. My parents did, in the Second World War and let me tell you, when I heard those stories, I realized that thatâs something that nobody should go through.
Climate change as well. We have to keep innovating because the climate keeps changing. I was just reading today in a Dutch newspaper that 2 degrees wonât be reached, it will be more. And in the Netherlands the land is so low, so that even with dykes, we will not be able to manage in the next 50 years. People will have to start moving. In the Indo-Gangetic Plains, theyâll have to plant short duration rice, use smart machinery such as the Happy Seeder, then plant short duration wheat â all just to stay ahead of the looming 50 ËC weather.
Do you agree?
Ibba: Well, yes, but I hope that in the end there will be good coordination between the CGIAR Centers and everything. But if it works well, then I definitely think that it will be more impactful. Thatâs for sure.
Kropff: What can supervisors and mentors do to encourage women in science careers?
Li: I think this is a good question Martin. I am sure that Itria and Thoko will agree with me: women need more than just our salary. I think that women are more emotional, so, most of the time, when my supervisor is more considerate and careful in regard to my emotions, I feel touched and actually, more motivated. I simply need more consideration, emotionally. I have some experience in this with students [who work for me]. When I want to stimulate their motivation, I compare the two effects. Say, I increase their salary. I feel that the male student is happier than the female. [Laughs] On the other hand, I try to be more considerate with all of my students and ask them about their families or express concern about something. When I do this, I donât get much of a reaction from the males but the females are grateful. I think the same works for me.

Kropff: I always intend to treat everyone equally and I think I do. But then some people need to be treated differently. That is situational management based on the capabilities and also the personality of people. Do we have to be more mindful of how one works with women?
Li: Well, people are diverse.
Kropff: Right. On the one hand, people should be treated as they want to be treated based on their individual personality, and then on the other hand you want to make sure that women are taken as seriously as men in, say, science.
Ndhlela: I agree with Huihui. Supervisors should give maximum support to women because they already have full plates. The field of science is challenging, so if they feel that theyâre not being given enough support, they tend to get discouraged and demoralized. So, supervisors and colleagues need to take that into account. Like Huihui said, women are more emotional than our counterparts. And they need that support. When dealing with women in a professional setting, supervisors could take a visionary style where they give us space to work and do our assigned duties without a lot of interference. Micromanagement is frustrating. From my experience, women in science are serious and they can work with minimum supervision and they are really out there to achieve objectives.
Ibba: I agree with both of you. Space and trust, and constructive criticism. Apart from the strength and support from oneâs supervisor, it would be good to implement a mentorship program for young scientists. Sometimes you need a non-supervisor voice or someone that can guide you [who you do not report to]. Human Resources also need to play a key role in supporting women and men, and ensuring zero discrimination. But Iâm sure that all we really want is to be treated as humans [laughs]. We all have emotions.
Kropff: Thank you very much colleagues for this open discussion. This has been very interesting and given me a lot of food for thought. Our conversation makes me miss pre-COVID-19 informal moments at work and at conferences, social moments where people open up. But here we show, we can do that during Zoom meetings as well with videos on to read each otherâs body language and with groups that are small. Thank you for the inspiration!
A multi-disciplinary team of agricultural researchers and development practitioners is proposing a new approach to tackle the shortcomings of global food production systems that degrade the environment, greatly contribute to climate change and fail to deliver healthy diets for a growing population.
The new methodology developed by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) aims to transform national food systems by achieving consensus between multiple stakeholders and building on successful participatory agricultural research experiences.
According to a peer-reviewed paper published today in the journal PLOS ONE, the Integrated Agri-food System Initiative (IASI) âis designed to generate strategies, actions, and quantitative, [Sustainable Development Goals] SDGs-aligned targets that have [a significant] likelihood of supportive public and private investmentâ.
The IASI methodology is based on successful integrated development projects implemented by CIMMYT in Mexico and Colombia, the latter in partnership with the Alliance Bioversity-CIAT, which engaged multiple public, private and civil sector collaborators in local maize systems enhancement. These initiatives took advantage of sociopolitical âwindows of opportunityâ that helped build multiple stakeholder consensus around health, nutrition, food security and development aspirations in both countries.
âCIMMYTâs integrated development approach to maize systems transformation in Mexico and Colombia laid the foundations of the IASI methodology by overcoming government transitions, annual budget constraints and win-or-lose rivalry between stakeholders in favor of equity, profitability, resilience and sustainability,â said Bram Govaerts, chief operating officer and Integrated Development Program director at CIMMYT.
Ultimately, the IASI methodology offers public officials and development practitioners the possibility to transform food systems by scaling out innovative farming practices and technologies that lead to sustainably managed natural resources and improved nutrition and food security.
The main steps to implement the IASI methodology are:
Diverse experts examine the current status and the business-as-usual scenario based on analysis of the socioeconomic, political, and sectoral context and model-based projections;
Stakeholders determine a preferred future scenario based on assessment of national implications, and define drivers of change toward a desired scenario;
Defined criteria are applied to stakeholder and expert inputs to validate drivers of change and to identify strategies and actions â for example, public policies, value chain and market interventions, and biotechnology applications â that can steer toward the preferred future scenario, which are then reviewed and prioritized by high-level decision makers;
Stakeholders agree on measurable targets and tangible, time-bound actions toward the preferred future scenario;
Stakeholders build shared commitment to a tactical implementation plan among traditional, non-traditional, and new partners;
Ongoing stakeholder engagement is organized around an online dashboard that tracks actions and progress toward targets and supports course correction and coordinated investment.
Following these steps, the authors of the IASI methodology propose to build a âglobal food systems transformation networkâ to co-design and co-implement agricultural development projects that bring together multiple partners and donors for global agricultural systems transformation.
As the approach is refined and further applications are built, it is expected that this network will harness efforts to initiate a new field of research and global practice on âintegrated methodologies for food system transformation and innovationâ â analogous to the fields of business administration and organizational development.
IASI serves as the backbone of new CGIAR Regional Integrated Initiatives, which draw on capacities from regional international agricultural research centers and programs to deliver global agri-food system transformation.
Popular starchy staples maize and wheat provide more than simple dietary energy, but they are often found at the center of debates around the excessive consumption of carbohydrates.
While the nutrient contribution of whole grains is commonly emphasized in dietary guidelines, the milling and subsequent processing of cereal products tends to reduce or remove much of the important protein, fat, vitamin and mineral content, and in recent years there has been increasing concern about the ultra-processing of cereal-based food products containing noxious dietary components that exacerbate the occurrence of non-communicable diseases.
For these reasons â and because of the focus on energy content â maize and wheat are not often considered to be among the categories of ânutrient-richâ foods that can contribute to reducing micronutrient malnutrition. Consequently, it is unsurprising that a popular perception that cereals make a limited contribution to nutritious diets persists. This view has not been successfully challenged by a necessarily nuanced understanding of the complex role of cereals, and particularly the carbohydrate fractions, in human nutrition.
âIn addition to the hidden micronutrients, there is sound scientific and popular awareness of the importance of some dietary components such as dietary fiber,â says Nigel Poole, Emeritus Professor of International Development at the School of Oriental and African Studies (SOAS).
âThough there is as yet imperfect scientific understanding and public awareness of the carbohydrates which make up dietary fiber,â he explains, âbiomedical research continues to highlight the importance of carbohydrates in health and well-being. Moreover, there is a need for further knowledge on the nature and roles of many other bioactive food components that are not usually considered to be nutrients.â
These bioactives are substances such as carotenoids, flavonoids, and polyphenols. Most of the beneficial effects of the consumption of whole grain cereals on non-communicable diseases are currently attributed to the bioactive components of dietary fiber and the wide variety of phytochemicals.
A growing body of evidence from cereal chemistry, food science and metabolic studies shows that the bioactives in cereals are important for nutrition, health and well-being. In a new working paper authored in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), Poole demonstrates that there is considerable potential for plant breeding strategies to improve these elements of grain composition. This could be done through exploiting natural variation, genetic and genomic selection methods, and mutagenesis and transgenesis in order to modify cell wall polysaccharides, and specifically to improve the starch composition and structure in breeding material through natural and induced mutations.
Rebalancing the agri-nutrition research agenda, Poole argues, is necessary in order to explore, explain and exploit the contribution to diets of hitherto less-researched nutrient-dense crops and other foods. Nevertheless, because of the quantities in which cereals are consumed, the nutritional contribution of cereals in addition to energy complements the consumption of micronutrient-rich fruits, vegetables, nuts and pulses in diverse diets.
To leverage the bioactive content of cereals â including dietary fiber â as well as the macro- and micronutrient content, a comprehensive approach to food and nutrition systems from farm to metabolism is needed, spanning research disciplines and food systemsâ stakeholders throughout the agri-food industries, and embracing policy makers, nutrition advocacy, and consumer education and behavior change.
